A method and an electronic device are provided, which attach or detaches two displays by magnetism. The electronic device includes a first housing including a first display exposed through a surface of the first housing, and a first cylindrical magnet disposed in a side of the first housing; and a second housing including a second display exposed through a surface of the second housing, and a second cylindrical magnet disposed in a side end of the second housing. At least one of the first cylindrical magnet and second cylindrical magnet is configured to rotate within the first housing and the second housing, respectively, by magnetic attraction of the first cylindrical magnet and second cylindrical magnet being adjacent to each other. The first housing and the second housing are coupled to each other by the magnetic attraction of the first cylindrical magnet and the second cylindrical magnet.
